Below is a list of Filter Media manufacturers from Carrollton, Texas. Filter media are materials used to remove or reduce the number of impurities in an air or fluid supply. Filtration products and equipment have two basic components: the filter and the media. The filter itself is the frame or housing mechanism that holds the media in place as a process stream is run through them. The media or material is responsible for the entrapment, collection or dissolution of impurities.
